How far will a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal and with a speed of 11.0 m/s? What is the maximum range that could be achieved with the same initial speed?

Step-by-step explanation:

It is given that, a stone travel over level ground if it is thrown upward at an angle of 30.0° with respect to the horizontal.

Speed with which it is thrown, v = 11 m/s

We need to find the maximum height above the ground level. The maximum height attained by the stone is given by :


h=(v^2sin^2\theta)/(2g)


h=((11\ m/s)^2sin^2(30))/(2* 9.8\ m/s^2)

h = 1.54 m

So, the stone will travel a distance of 1.54 meters.

Range of a projectile is given by :


R=(v^2sin\ 2\theta)/(g)


R=((11\ m/s)^2sin(60))/(9.8\ m/s^2)

R = 10.69 m

So, the maximum range achieved with the same initial speed is 10.69 meters. Hence, this is the required solution.
